Public bug reported:
This bug originally exhibited itself as: Macbook Pro 5,2 trackpad
spurious input, jumps to horizontal screen edges
While typing the mouse occasionally jumps horizontally to the edge of
the screen. It is not consistent which edge it jumps to. I notice this
due to xmouse.
I believe this is due to the touchpad being overly sensitive. By
tapping the very edges of the trackpad (similar to how my palms might
touch the trackpad while typing) I am able to sporadically reproduce
this behavior. As such, I believe that this can best be fixed by the
trackpad driver either watching for this kind of behavior while typing,
or the 'Disable touchpad while typing' option (which I have enabled)
having an increased timeout.
Actually, now that I test this, I'm able to use the touchpad while
holding down keys on the keyboard. This bug should almost certainly be
applied against the maintainer of that package, as that option is not
respected on this laptop.
